Position Summary/Overview:
This is a hands-on, senior-level full-stack engineering and architecture role responsible for the design, development, modernization, security, and operational quality of HealthCare Partners’ web and application portfolio. The position serves as the technical owner for application development and provides durable, accountable technical leadership for this function — roughly 80% hands-on engineering as the “pro-code” lead and 20% architecture and strategy in partnership with management.
HealthCare Partners is primarily a Microsoft shop — SQL Server, Azure SQL, and Fabric Databases; .NET, C#, and ASP.NET MVC 5; and React.js with TypeScript powering the front end of our external portals and WordPress the same for our public website. As the senior technical owner of application development, you operate independently, set technical direction, mentor engineers, and translate business needs into well-architected, secure, and maintainable solutions in a healthcare-regulated environment.

Essential Responsibilities
1. Application Engineering Leadership & Pro-Code Ownership

• Serve as the “pro-code” lead, setting the bar for code quality, design, and engineering practice across the portfolio
• Define the strategy, standards, and multi-year roadmap for Application Engineering
• Own technical decisions on frameworks and patterns and act as the senior escalation point for complex application issues
• Define coding standards, reusable patterns, and documentation; mentor engineers and raise overall engineering maturity

2. Full-Stack Application Development

• Design and build full-stack applications using .NET / C#, ASP.NET MVC, and React.js
• Develop and consume RESTful APIs and web services that integrate internal systems and third-party platforms
• Apply automated testing and code review to deliver maintainable, well-tested features

3. Secure Development & SDLC

• Champion a “shift-left” approach — security designed into the architecture and written into the code from the outset
• Leverage Azure DevOps and GitHub Enterprise with automated code, secret, and vulnerability scanning in CI/CD
• Use Azure Key Vault for secrets so no sensitive information is stored within deployed applications
• Apply secure-by-design and secure-coding standards, and support annual security reviews and penetration testing

4. AI-Enabled & Agentic Development

• Use AI-assisted and agentic development tools (e.g., GitHub Copilot, Claude) as a routine part of building, refactoring, and generating tests
• Apply AI to discovery — rapidly understanding and mapping existing and legacy solutions to accelerate onboarding and modernization
• Generate and maintain technical artifacts (design docs, API documentation, runbooks) that stay consistent with the implementation
• Apply AI pragmatically and responsibly — reviewing output for correctness, security, and PHI/compliance — and pilot new agentic scenarios (e.g., automated code review, migration and test scaffolding)

5. Application Modernization & Cloud Migration

• Modernize legacy ASP.NET MVC 5 applications to .NET 10, deployed as Azure App Services
• Migrate on-premises apps from Windows Authentication to Microsoft Entra ID, preserving seamless SSO with no credential prompts
• Apply relevant Azure resources (App Service, Functions, API Management, App Configuration, networking) to stand up web apps in Azure

6. Integration & Interoperability

• Integrate with third parties via FHIR and web services using secure, standards-based data exchange
• Implement interoperability patterns — FHIR (R4) and REST, with awareness of HL7 v2.x and X12 EDI (270/271 eligibility, 837/835 claims, 278 authorizations)
• Apply OAuth2 / token-based authentication and build resilient vendor and payer integrations

7. Database-First Engineering & Performance

• Develop database-first, with the proficiency to reason about query performance and execution behavior — not just rely on the ORM
• Use Entity Framework and Dapper appropriately, and judge when to use database views, functions, and stored procedures versus application code
• Partner with the Senior DBA and data engineers to validate designs, tune queries, and ensure performant, reliable, compliant data

8. Observability & Operational Excellence

• Use Application Insights / Azure Monitor as the basis for consolidating exception handling and usage reporting across applications
• Instrument for reliability and diagnostics; proactively identify and remediate performance, reliability, and security risks

9. Collaboration, Requirements & Solution Guidance

• Partner with the Project Managers and Business Analysts in Delivery & Enablement, and with business areas, to understand requirements
• Guide stakeholders toward solutions that make sense, translating business needs into pragmatic, well-architected approaches

• Modernizing legacy applications to .NET (current LTS — .NET 10) on Azure App Service, including Entra ID SSO migration

• Secure development (shift-left) and CI/CD with Azure DevOps and/or GitHub, including automated code, secret, and vulnerability scanning
• Application Insights / Azure Monitor; ability to work independently, lead technically, and mentor; clear written and verbal communication

Strongly Preferred

• FHIR and healthcare interoperability (HL7, X12 EDI such as 270/271, 837/835, 278)
• Experience in HIPAA or comparable regulated environments
• Azure resources for web apps (App Service, Functions, API Management, Key Vault, Microsoft Entra External ID (formerly Azure AD B2C)); security reviews and penetration testing
• Fluency with AI-assisted / agentic development tools (e.g., GitHub Copilot)

Nice to Have

• WordPress
• SMART on FHIR, Da Vinci, or awareness of CMS interoperability mandates
